wifi: iwlwifi: mvm: fix regdb initialization

In order to get regulatory domain, driver sends MCC_UPDATE_CMD to the
FW. One of the parameters in the response is the status which can tell
if the regdomain has changed or not.

When iwl_mvm_init_mcc() is called during iwl_op_mode_mvm_start(), then
sband is still NULL and channel parameters (i.e. chan->flags)  cannot be
initialized. When, further in the flow, iwl_mvm_update_mcc() is called
during iwl_mvm_up(), it first checks if the regdomain has changed and
then skips the update if it remains the same. But, since channel
parameters weren't initialized yet, the update should be forced in this
codepath. Fix that by adding a corresponding parameter to
iwl_mvm_init_fw_regd().
